I have this ADSL modem/router: pirelli drg-A221g (bit.ly/107drdY) It has one RJ-11 (ADSL Phone line) input, one output to telephone headset, and only one RJ-45 (Ethernet/lan) connection on it.
It works fine, when I am using ADSL, and I can connect several devices to it wirelessly. Now, I want to disconnect it from RJ-11 (ADSL line), connect its RJ-45 (lan) to internet connection cable (from other company), and use it only as a router to access to internet wirelessly. I want to connect my internet cable (coming from TV-cable-modem-box) to this router and have wireless internet in my laptops and mobiles. But it does not work!
I connect internet cable from tv-cable-modem-box to my laptop and it works ok. Then I tried connecting this cable to the only RJ-45 port on the router. All devices successfully connect to the router, but there is no internet!
After doing several restarts in the router, laptop and tv-cable-modem-box, (only restarts, no configuration or settings), I could get internet on my laptop. But still, my other devices are connected to the router, with no internet.
Can someone help please? Thanks

@Ramhound, I have internet connection via LAN cable. When I connect this lan cable to RJ-45 port on the ADSL Modem/Router, after some restarts, I get wireless internet in one of my laptops. But my other laptop and mobile phones, although they are connected to the same router, they do not have internet.
Any solution? – cybergeek654 – 2013-05-03T13:51:30.207
@Ramhound DUDE it is not an ADSL modem. It is an ADSL modem/router. He said that. i.e. one of those devices that is both a router and a modem. You might've seen one, as loads of homes have one. It may even be the most common thing provided by ISPs. – barlop – 2013-05-03T14:13:45.530
1@cybergeek654 have you dealt with NAT and DHCP so there's no clash? Like, only one device doing DHCP, and I guess you want your modem/router device to do NAT. And you may as well have your modem/router do DHCP. – barlop – 2013-05-03T14:16:59.467
@Ramhound Actually, maybe some can. I think i've done it before, and the manufacturer was on the line at the time and said it might work though is not designed for that. They're not really designed for that. It can work. It's wrong to say as you did "ADSL Modem as only a router" He is talking about a modem/router device. It's a better idea to use a plain router 'cos he'd be using the device in a way not intended. I've done it before though. The LAN ports aren't obviously just "output" and they don't work like "input internet"!! – barlop – 2013-05-03T14:19:45.100
@barlop - The author's device can't The device in question is a ADSL modem that has 802.11 capabiltiies. Even if the device was some other device it would need a RJ-45 wired as an internet port. I made an error in my original comment. The internet is handled by the RJ-11 port not the RJ-45 port. – Ramhound – 2013-05-03T14:20:57.980
@Ramhound "The author's device can't " That's a little different to what you said earlier which was more general. And I think that is a reasonable possibility, particularly judging by the fact that he's saying it's not working for him, and that some can some can't. BUT, he said one computer has a connection. – barlop – 2013-05-03T14:22:48.253
I tried to join the chat, but apparently I do not have enough reputation in this forum :(
Anyway, I DID get internet in one of my laptops, wirelessly connected to my ADSL Modem/router. (and that ADSL modem/router was NOT connected to phone line. It was connected to internet through its only LAN port).
Now, my question is what should I do to have internet in my other devices, wirelessly connected to my ADSL modem/router? – cybergeek654 – 2013-05-03T15:00:27.083
@barlop, Thanks for the response. What you are saying about NAT and DHCP sounds to be a solution to my situation.
Would be please explain to me what should I do? I have access to the control panel of this ADSL modem/router. What should I set there and also in each device? – cybergeek654 – 2013-05-03T15:06:50.693
